ENGINE HEALTH

MANAGEMENT

Since 1989, Southwest Research Institute® (SwRI®) has provided jet engine health management solu-

tions for the U.S. Air Force, Army, and original equipment manufacturers (OEM). SwRI is a recognized leader in develop-ing innovative solutions and providing independent engineering assessments, including:

• Engine Health Management Plus (EHM+) • Engine Trending and Diagnostics (ET&D)• Technical manual development• ET&D training

SwRI’s success in EHM is based on a multidisciplinary systems engineering approach to problem solving. Comprehensive expertise in design, modeling and integration enables SwRI to address client needs.

SwRI has implemented an AS9100 Quality Management System for all design and manufacturing processes, including engineering analysis tasks and software development.

Engine Health Management Plus (EHM+)

Working closely with the U.S. Air Force, SwRI supports EHM+ to reduce engine maintenance, repair and overhaul costs and engine downtime. ET&D uses histori-cal engine performance and maintenance data to develop trends that are used to determine engine performance and identify potential engine failures before they occur. EHM+ uses ET&D and Reliability Centered Maintenance (RCM) concepts to improve performance. EHM+ data is warehoused and accessible over the Internet.

Engine Technical Manuals

SwRI engineers use their operational understanding of engine control systems, sensors and signals, and engine trending software to develop engine performance analysis methodologies for the following engines:

• F100 • F110 • TF33 • F101 • F118 • TF34 • F108 • T56 • TF39

Development of the methodologies requires research of engine parameters and their correlations, and review of maintenance that affects engine perfor-mance trends. The methodologies are documented in Technical Orders that instruct USAF personnel on how to trend and analyze a specific type/model/series engine.

Engine Trending and Diagnostics Training

SwRI has developed courses on EHM+ concepts for the following engines:

• F100 • F108 • TF33 • F101 • F110 • TF34

SwRI works closely with the USAF Air Education and Training Command (AETC), other MAJCOMs, USAF engi-neers and OEMs to develop the courses, following the Air Force Instructional System Design (ISD) process, and trans-fers the course material for AETC to con-tinue providing the training after the first year of delivery by SwRI. Course content includes relationships of engine parame-ters, trending concepts and terminology, and use of available software tools to perform EHM+ related job duties.

SwRI develops and delivers ET&D training to USAF engine maintainers.

SwRI works closely with the U.S. Air Force to provide jet engine health management for various engine models including (from top) F110, TF33, F118, F100,

TF39 and F108.
